A PROTECTIVE ST ~PVE
FIELD OF TH~ INVEN~ON
The present invention relates to a sleeve for protecting the arms of a wearer from contact S with liquids that otherwise might have an adverse effect on the skin of the user.
There are many ch. where it is desired to protect the arms from contæt with fluids that have an adverse effect on the skin of the user. This is p~li~uLuly the case where caustic or æidic solutions are used for cleaning. The difficulty generaDy does not arise where the hands are immersed into a bucket of cleQning liquid because water impervious gloves are usuaOy worn, but rather where the hands are lifted above the horizontal and cleaning liquid runs down the gloves onto the arms.
It is known to provide for protection of the forearm, or even up to the shoulders ir~ the form of a plastics sleeve but this protection is only mtended to maintain cleanliness of the foreQrm. The use of a plastic sleeve however does not alleviate the problem of keeping liquid of the arms and such plastics sleeves only protect against a minimal amount of spill before cleaning liquid streQms down the arms beyond the end of the plastics sleeves.
It has been suggested before to construct gloves that include a layer for retaining water on the outside of a water ' . ' ' layer. The water retaming layer however is simply on the glove to æt in much the same way as a sponge. so as to apply cleaning preparation without having separQtely to use a sponge. Examples of such j LL' ~
can be found in British patent application GB2113977 and British apphcation GB
899016. Scourer pads have also been suggested for use with such gloves, to add to their usefulness such as in British patent application GB2033731 or as in British Patent 21343171 to Koumbas. These gloves however are primarily concerned with applying cleaning fluid to the surfæe that requircs cleaning, and have no regard for the more awkward problem of liquid running down a raised arm. In fact the use of such gloves , the problem because larger amounts of liquid are i , ''y retained and ~lu~ ,ly released down the arm.
It has also been suggested in Australian Patent ~ ... 490155 (73535/74) to 35 provide a surgical gown which includes a central operative field of the front panel of the gown having a fluid impervious material having an absorbent outer surfæe to absorb fluids that might come in contact with the central operative field. Use of an absorptive layer on the gown is said to minimise the amount of liquid run-of WO 95131118 " ~ ~ PCT/AU95100277 .,`'~'~` .''` -Tbere has however, to the inventor's knowledge, not been anarticle to provide prooection to the arms of tbe wearer, that is convenient to use with gloves, that provides t for secure and close fitting over the``arm, is easy to car y, and to put on and discard, or S to fit all user sizes. ;~
Accordingly it is an object of this invention to provide a protective sleeve that protects arms of a user against unwanted contact with a fluid that obviates or minimises any one of tbe ~f ~ problems in a simple yet effective way, or at least provides the 10 public with a useful choice.
SUMMARY OF THE ~VENTION
In a broad form and not necessarily the broadest or only forin the invention could be said to reside in a protective sleeve including fastening means to fasten around an arm lS of a wearer so as to be retained in position, said protective sleeve including an mner layer of watet proof material extending the length of the sleeve, an outermost layer of absorptive material covering said inner layer . ;.~ ly so as to retard liquid run off along the sleeve, said sleeve extending to the upper arrn of the user..
20 The fastening means may be in tbe form of an elasticised section that fits around tbe wrist of the wearer. Cu,.., 'S/ the sleeve is fitted over the arm and secured, and waterproof gloves are fitted over the outer end of the sleeve so that there is ~""~
overlap ~ a sealmg fit of the sleeve over the arm is not required.
25 Alternatively the fastenmg means might include a loop that hooks over the thumb of a user, thereby preventing travel of the sleeve away frûm the hand.
In a preferable form the absorptive layer is subst mtialiy coextensive with the water proof layer. Most preferably the sleeve is formed from a lammate of waterproof and 30 absorptive material, the laminate being produced before the sleeve is formed.
It is to be lln~i~rcl,-o~i however, that the absorptive material may simply be adhered to a waterproof sleeve with a suitable plastics adhesive. The absorptive maoerial may be of any material that is absorptive, and generally it is intended that the sleeve is re-useable, 35 the absorptive material is " ,,~1 preferably somewhat rt sistmt to water and/or the liquid being used and may be of a woven fabric.

It may be desired to have rather Lhicker absorptive material however not co-extensive with the sleeve but rather formed in bands formed around the sleeve. The absorptive material of these bands may be in the form of a sponge-lil;é material.
5 The waterproof material is preferably a plastics or rubber material, such as are already used for protective sleeves, or gloves. In one form the plastics of the sleeves is of a material that whilst water resistant is sLII able to allow passage of some air so that the sleeve is breathable.
10 In an alternaLive form a chemically resistmt layer is also provided which is resistant to chemicals for which the sleeve is mtended for use with. The chemically resisL~nt layer may be separate from the waterproof layer or it may be integral with iL
It may be convenient to produce the protective sleeve integrally with a glove. It is 5 envisaged that the glove portion would not include an absorptive layer, because the absorpLive layer would lead to an increase in liquid spilling down the sleeve.
Whilst certain indication have been given relating to the scope of the invention it is to be understood that the invention may reside im two or more of these mdications combined.

DETAILED DESCRlPrlON OF THE ILLUSTRATED EMBODIMENTS
The protective sleeve of this invention comprises an inner layer (1) of waterproof material extending along the length of the sleeve, and an outermost layer (2) ofabsorptive material that covers the inner layer ~,il. r ' lly~ SO that liquid running 30 along the length of the sleeve absorbs into the absorptive layer and the running off is at least retarded.
The first ~ bo~l ~ 1 illustrated in Figure I and hgure 2 comprises two layers, a water prûof plastics layer I on am imside of the sleeve that acts as a support for an absorptive 35 layer 2. An outer end of the plastics layer is folded over and an elastic member 3 is irlserted in the channel 4 so formed. The channel is sewn closed. The elasticised outer, hamd proximal end (5) of the sleeve acts to hold the sleeve in position on the wrist of the user.
~ WO95/31118 2 1 90oo~ IJ J
The irmer, or hand distal (6) end of the sleeve extends to the shoulder of the user, and is also elasticised in a manner similar to that on the hand proximal end to be retained on the shoulder of the user. It may be desired to provide for a further fastening means for 5 the inner end, for exaunple it may be desired to have a band extending from the inner end around the shoulder of the user, so as to maintain the sleeve as high up on the arm as is practicable. The length of the sleeve is illustrated as being up to the shoulder.
The absorptive material shown in this ' " is substantially ~ .t~ ;v~, with the 10 plastics material, except at the outer end of the sleeve there is no absorptive material covering the elasticised portion, so that liquid is not retained on the stitching of the sleeve. It is to be understood that the invention also ~"~ forms where the absorptive material is not co-extensive with the water-proof material.
15 The absorptive material in this ' ' is a flannel material adhered to a plastics sleeve using an adhesive layer (7) . A laminate so formed is preferable to having the flarmel separate from the plastics material, because where there is no laminate type structl}re there are portions of the sleeve where the flar~nel material is not in contact with the plastics material and the liquid can progress along the sleeve much more rapidly.
In use the sleeve is fitted onto the arm of the user and the hand distal end (6) is secured to the shoulder, which term is intended to include the upper parts of the arm close to the shoulder. The hand distal portion of the sleeve is securely fitted to the wrist. A water proof glove is then put on and the sleeve and glove is ready for use.
When the arm is raised the sleeve is particularly effective, in that water or other cleaning liquid will run off the glove onto the sleeve and become absorbed by the flannel of the absorptive layer. It will be understood the capacity of the sleeve to absorb liquid is not ir~mite and that where great amounts of liquid are to be used then the moisture will 30 exceed the capacity of the outer layer to absorb.
Whilst a plastics layer is used on the flannel, it may be preferred to coat the flannel or other absorptive layer with a water ~ ' ' coating thereby forming an ,. ., ~ . layer.
A second i ~o~' of the invention is illustrated in Figures 3 and 4. This comprises a plastics layer (I) which is quite separate from the water absorptive layer (2). This sleeve is imtended more as a disposable sleeve so that the outer layer is simply a layer of WO 95/31118 ~' PCIIAU95/00277 l~9OOOa i- -absorptive paper. Instead of having the two layers adhered together the layers are joined only at the two ends (5, 6~ o~ the sleeve. An elasticised band (4) as well as aligned ends of the plastics and .paper layer are over sewn together, as is best seen in figure 4.
S
Whilst it is a slight ~ that the two layers are not contacted together, there isstiLI sufficient contact between the two layers along the length of the sleeve such that moisture does no simply soak through the absorptive layer close to the glove and run along the plastics layer with minimal moisture absorption. In use, the two layers do not 10 represent to well formed cylinders, but they have a ~r... :.1. . ,.1.1~ number of folds and cmves as a result of the complex shape of a dynamic arm and ~ a great number of contacts are made between the two layers.
The length of the sleeve is somewhat shorter than that of the first r~mh ~ ' t, and 15 extends past the elbow of users. The hand proximal end of this ~,...L ~ " is intended to end ~ , half way between the elbow and the shoulder. This is found to be a uu..,;~ more . . . ~ to wear, leading to more secure fitting aroumd the upper part of the arm. GeneraLly when the arm is lifted to during cleaning, generally the elbow is stiLI bent, so that generally the greatest amomnt of water flow is 20 on the forearm of the user, only very rarely does liquid contact the upper arm.
Cr , 'y it is of ' "~! greater importance to protect the lower arm (10) of the user rather than upper arm ( I l).
A third ' ~rlimPn~ of the invention is illustrated in Figures 5 and 6. This ... ~hn.l ......
25 comprises a combined sleeve and glove (13). The gloYe comprises a suitable water resistant material that is sufficiently robust to withstand the use to which it is to be put.
No absorptive layer covers the glove. A sleeve portion (14) of the glove comprises a water resistant layer that is integraUy formed with the glove portion. The absorbent layer is formed onto the sleeve portion by a heat welding process giving a stippled look.
30 The heat welds (15) being patterned over the sleeve. The hand distal portion of the sleeve is gathered as for the other illustrated; ' - ' and has an elasticised band attached.
This ~ ,bo li ~ ~ has the advantage that separate gloves need not be used, and that only 35 one item needs to be domned for each arm and hand. The glove portion is not covered with an absorptive layer because that would lead to a greater supply of residual liquid to un off down the sleeve. One difficulty however is that different sizes may be needed depending on the hand size of the user. Whilst the illustrated third i ' ~ " shows WO9~1118 2 t 900~g PCTIAU9i,002M
7 ' ' S
a sleeve portion that extend to past the elbow of a user and not to the shoulder, it may be desired to have a shoulder length sleeve portion in connection with a glove.
.. ..
It is to be understood that the stippled heat welded double layer is ad~a..~,~ in that S tbe two layers are held in close proximity whilst not lequiring the expense of forming an adhesive layer ~ el,.,~ or a laminate. It is also to be understood that tbis material may be used in ' " of the sleeve having no glove and that other double layers may also be used. r, the sleeve portion need not be integrally formed with the glove and may be joined provided that the join is water proofed.
A fourth . '~o.l,.... 1l of the invention is illustrated in Figures 7 and 8. In tbis l~lho~ thewaterprooflayer(l)formsthesleeve~ Theabsorbentlayerisprovided in the form of bands (20) that are spaced apart I -, ' lly along tbe sleeve. Thebands of absorptive material comprise a sponge material and are shown as being 15 ~ ,ly thicker than the absorptive layers shown in the other ~ The bands of sponge are ~ 'y 7mm thick. This 1~ " has the capacity for absorbing a ~ n rlr . ~ volume of water. Each of the bands acts as a barrier to flow of liquid where a greater quantity of liquid is anticipated. r~ the bands act tospread the flow of water laterally so that unlike where a layer of absorptive paper is 20 used streams of water will be rapidly spread and more easily absorbed.
This sleeve is shown as the same length as that of the third; ' - " and as with the third . ..I .o.: .. this may also take the form of a shoulder length sleeve.
25 Additionally where a ~ . : 1 . ..1,1. flow of liquid is anticipated it may be desirable to provide a continuous absorptive layer such as described in anyone of the first tbree illustrated Pmhc ' together with a banded layer such as described in the fourth on top of the continuous layer.
30 Otner ~ of .' absorptive layer may also be provided.
Whilst only a two layered ,. " ,., ,c,.. 1 has been shown, it may be desirable to have more than two layers, provided that tbe outer layer is absorptive. and that there is a layer intemal of the absorptive layer that is . ' ' to liquid. It may be desirable 35 for comfort to the wearer to provide a three layered sleeve, where an intemal absorptive layer is also provided to take up moisture intemally of the sleeve, for example from

30 The heat welds (15) being patterned over the sleeve. The hand distal portion of the sleeve is gathered as for the other illustrated; ' - ' and has an elasticised band attached.
This ~ ,bo li ~ ~ has the advantage that separate gloves need not be used, and that only 35 one item needs to be domned for each arm and hand. The glove portion is not covered with an absorptive layer because that would lead to a greater supply of residual liquid to un off down the sleeve. One difficulty however is that different sizes may be needed depending on the hand size of the user. Whilst the illustrated third i ' ~ " shows WO9~1118 2 t 900~g PCTIAU9i,002M
7 ' ' S
a sleeve portion that extend to past the elbow of a user and not to the shoulder, it may be desired to have a shoulder length sleeve portion in connection with a glove.
.. ..
It is to be understood that the stippled heat welded double layer is ad~a..~,~ in that S tbe two layers are held in close proximity whilst not lequiring the expense of forming an adhesive layer ~ el,.,~ or a laminate. It is also to be understood that tbis material may be used in ' " of the sleeve having no glove and that other double layers may also be used. r, the sleeve portion need not be integrally formed with the glove and may be joined provided that the join is water proofed.
A fourth . '~o.l,.... 1l of the invention is illustrated in Figures 7 and 8. In tbis l~lho~ thewaterprooflayer(l)formsthesleeve~ Theabsorbentlayerisprovided in the form of bands (20) that are spaced apart I -, ' lly along tbe sleeve. Thebands of absorptive material comprise a sponge material and are shown as being 15 ~ ,ly thicker than the absorptive layers shown in the other ~ The bands of sponge are ~ 'y 7mm thick. This 1~ " has the capacity for absorbing a ~ n rlr . ~ volume of water. Each of the bands acts as a barrier to flow of liquid where a greater quantity of liquid is anticipated. r~ the bands act tospread the flow of water laterally so that unlike where a layer of absorptive paper is 20 used streams of water will be rapidly spread and more easily absorbed.
This sleeve is shown as the same length as that of the third; ' - " and as with the third . ..I .o.: .. this may also take the form of a shoulder length sleeve.
25 Additionally where a ~ . : 1 . ..1,1. flow of liquid is anticipated it may be desirable to provide a continuous absorptive layer such as described in anyone of the first tbree illustrated Pmhc ' together with a banded layer such as described in the fourth on top of the continuous layer.
30 Otner ~ of .' absorptive layer may also be provided.
Whilst only a two layered ,. " ,., ,c,.. 1 has been shown, it may be desirable to have more than two layers, provided that tbe outer layer is absorptive. and that there is a layer intemal of the absorptive layer that is . ' ' to liquid. It may be desirable 35 for comfort to the wearer to provide a three layered sleeve, where an intemal absorptive layer is also provided to take up moisture intemally of the sleeve, for example from
Claims (16)
1. A protective sleeve including fastening means to fasten around an arm of a wearer so as to be retained in position. said protective sleeve including an inner layer of water proof material extending the length of the sleeve, an outermost layer of absorptive material covering said inner layer circumferentially so as to retard liquid run off along the sleeve, said sleeve extending to the upper arm of the user.
